JOINTING AND TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 357,622, dated February15, v1887. Application filed May 29, 1885. Serial No. 166,995. (Nomodali) To all whom t may concern:

Beit known that I, EDWARD K. YPATTEN, of Utica, in the county of Oneidaand State of New York,have invented certain new and useful Improvementsin .Iointing and Trimming Machines; and I do hereby declare that thefollowing is a-full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, referencer being had to the accompanyingdrawings, and to theletters of refer'en ce marked thereon, which formpart of this specication.

My invention relates to that class of machines constructed for planing,trimming, jointing, and truing the sides, ends, edges, or angles ofboxes, drawerslumber, and other articles where a true edge is required;and it consists in arotating head or heads carrying cutting-spurs andcutters mounted on independent shafts, in a feeding device for feedingthe article to be operated on, and in other combinations and mechanicaldetails hereinafter pointed out. Y

In the accompanying drawings similar letters of reference refer tocorresponding parts throughout the several views.

Fig. 5 is a side viewof a feeding device and a section of the frame. Fig. 6 isa plan view ofthe same. Fig. 7 is an end view of the feeding device and the section ofthe frame. Fig. 8 is a front view of the rotating head, showing thelocation and construction of the spurs and cutters in the face of thehead. Fig. 9 is a section view of the head and a side view of thepulley, the` broken lines indicating a section of the upright. Fig.v 10is a view of the cutting-spur. Fig. 11 is a side view of a cutter. Fig.l2 is an end view of the cutting-spur and a section of the head,exposing the retaining-bolt for securing the cuttingspur to the head.Fig. 13 is a side view of the retaining-bolt, and Fig. 14 is a top viewof the same.

Having described my invention by reference to the figures represented inthe accompanying drawings, I will nonr proceed to describe the same byreference to the letters marked thereon.

The machine represented in the drawings is constructed for truing,trimming, and smoothing opposite ends or sides of drawers, boxes, orother lumber. I do not, however, intend to limit myself to the use towhich this machine may be applied, nor to the man ner of constructingthe same, as it is obvious that the rotating head or heads, carryingsuitable spurs and cutters, may be used in a variety of ways notillustrated for jointing, truing, and planing sides or angles of lumberwhere a plane or true edge is required. and maybe accomplished by asingle or by double heads, as the case may require.

For trimming, planing, matching, smoothing, and truing the oppositesurfaces of articles, I provide two heads mounted, preferably, onindependent shafts journaled in stationary or movable uprights forsupporting and carrying the rotating head. In the draw ings the headsare mounted to be rotated vertically, and are driven by belt-s runningon Suitable pulleys driven from the main line of shafting.

The working parts of the machine are shown mounted on frame A consistingof four legs united by suitable cross-ties, as shown, but which may beof any other suitable and convenient construction.

B and B represent heads in which are secured spurs.

b b b b represent four spurs or cutters, the spur ends forming acutting-surface and extending beyond the periphery of the head forforming a cuttingsurface in line with the face of the spurs. Thesespursare let into the face of the head by dovetailed grooves b b b b. One ormore of these spurs may be used. The spurs are fitted into the groovesand held by bolts b2. The projecting ends of the spurs should be broughtto a sharp cutting-edge.

b4 represents cutters set in the face of the rotating heads,substantially in line with the spurs and extending beyond the peripheryof the head to a point substantially in the same circle with theprojecting ends of the spurs. These cutters are provided withcuttingedges, as indicated in Fig. 11, and are set in the headsubstantially at right angles with the spurs IOO for cutting andcleaning the material cut and f trimmed by the spurs.

The cutters are held in grooves in the hcad by bolts substantially likethat shown in. Fig. l5. In the drawings the heads are shown circular.While this form is preferable, those having angles may be used, thespurs and cutters being set in the projecting angles ofthe head. Theseheads provided with the spurs and critters are mounted ou shafts c a andare held rigidly thereto by nuts or keys, or botlnand are mountedinjournals c a ac in the upper ends of upright-s D D,and are driven bypulieys a? arigidly held on the shafts by belts running on drum K,journaled in the frame connected with drivingpulley P, which isconnected with the mainline ofshafting, for imparting a rotating motionto the heads carrying the spurs and cutters.

To adjust the heads to different-sized arti cles to be operated ou Iprovide movable uprights D D, which are mounted on rods e e, which passthrough the uprights at c' e e' c', which siide on the rods, which arerigidly held at their extremities e c3 c c3 in the frame. In the dr.wings the right-hand upright', D, issecured rigidly in position on thesupportingrods by set-screws e* e, the left-hand upright being movableto secure the proper adjustment by adjustingscrew e5, one end working insuitable bearings in the righthand upright and the opposite end in theframe at e", and is operated by hand wheel e? for turning thescrewthreads in the left-hand upright for horizont-ally moving the sameto secure accurate adjustment.

I disclaim the use and construction of a trimming-machine provided withfour raised ways, with a movable carriage mounted thereon, two uprightsin which are mounted to be operated in parallel lines, two circularsaws, with a right and left hand screw for moving the saws to or from acommon center in the same right line, the said carriage moving betweenthe saws for feeding the article to be operated thereon.

For feeding the article to be operated on between heads carrying thespurs and cutters for simultaneously operating upon opposite angles, Iprovide tracks ff,with cross-grooves ff, (shown in Fig. 5,) let into thesame on the under side thereof. These grooves fit projecting danges f,Fig. 2, on the upper surface of the frame. In the drawings the righthandtrack is held rigid by set screw f 3. The left-hand track is attached tothe movable upright by braces fj and moves therewith. On the uppersurface of the tracks are projecting flanges f 5 f 5. Itis obvious thateither or both of these might be secured to the uprights, if so desired.On the upper surfaces of these tracks are provided carriers Gr G, on theunder side of which is a groove to tit the projecting Bauges f 5 f 5,for securing accurate movement. On the rear of each carrier is aprojecting surface, g, (shown in Fig. 5,) asimilar one being provided oneach, against which the article to be operated on is driven by screws gg', working in bearings g2 y, operated by hand-wheelg3.

Operation: The operator sets the rotating heads to suit the article tobe operated on. The article is then placed on the carriers and crowdedagainst projections g g, and rigidly clamped by turning thehandwheelsg3g The operator then crowds the article and carriersforward,which are moved in accurate liuc on the flanges on the uppersurface of' the track until the article is passed between the rotatingheads carrying the spurs and cutters. 'Ihe carriage and article are thenreturned and the article removed from the machine.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is

1. In amachine for planing,trimming, jointing,and truing the sides,ends, edges, or angles of boxes, drawers, lumber, and other articleswhere two edges are required lto be parallel with each other, thecombination of two heads mounted in two uprights and constructed to berotated in the same direction in parallel planes, each head carrying oneor more cut ting spurs,and one or more clearingcutters,ar rangedsubstantially as described,f`or the purposes stated.
